' A j CUTTING IMLEMENT Application led'Ma'y 11, 1923. Serial No. 638,411.

To all whom t mag/concern.: v

Be a known that I, JOHN kTOQMY, a Cai.--

zen of the United States,l and a resident of Coscob, inthecounty of Fairfield and State otv Connecticut, have invented a new and Improved Cutting Implement, of which the following is a full,clear,pand exact description. j

This invention lhasrelationto cutting implements, the principal objectin view residing in the provision ofa cutting implement which is adapted for stationary attachment to a supporting surface such as a workbench, machine, table, bench, or `the like whereby to eliminate its'displaeement or loss 1 and `in order that the same will always remain within convenient use of the user.

'As a further object the invention contemplates a cutting implement vin which. the. blade having cutting edges is so associated with the housing that the same may be exposed for use by projection from the housing d the cheapness with which it may bemanniacturcd and applied and the facility with `which it may be employed for the purpose intended. i

lWit-h the above recited and'other objects in View the .invention resides in the novel construction set forthin` the following specification, particularly pointed'out in theyap-T pended claim and illustrated in'thejaecofmi t panyingdrawing, it being understood ythat the right is .reserved tojembodiments other kthan those actually illustrated kherein to the full extent indicated by the general meaning of the terms in which the claim iseXpressed. In the`drawing-- i. n t j' Figure'l is a perspective View of the device in applied position to a supportingsurface with the blade projected from its easing or housing to exposethe cutting edges for use.

`Figf2 is asimilar viewy `with the vblade in retracted position for covering and protecting the cutting edges.

, Fig. 8 is a transverse sectional view therethrough. Referring to the drawing by characters of reference, 10 designates a supporting surifacesuchk as a bench, table, machine or the like-upon which the cutting implement constituting the invention is mounted. The cut- .ting implement consists of a housing including a plate or upper wall 11 which isv provided with depending -side 'lianges or walls 12 from its opposite longitudinal edges. Laterally projecting apert-ured ears 13 are `provided Iat the lower outer sides of the side walls or ianges 12 to receive therethrough fastening elements such as screws 14 which are anchored into the supporting surface whereby the housing is stationarily or fixedly associated therewith, the upper wall or plate 11 being disposed parallel and in spaced relation thereto. The upper wall or plate vl1 is provided with a central longitudinal slot 15 extending inwardly from one end thereof and terminating short of the op-v posite end.` The implement further includes a blade 16 which is provided at one extremity with a cutting edge or edges 17. The body of the blade is of an appropriate width to snugly fit between the side walls or anges 12. The blade is associated with the under side of the plate or upper wall 11 tor f longitudinal sliding movement or adjustments relative thereto by a bolt 18 having a head 19 at one end of its shank, which shank at vits juncture with the head is provided with a non-circular or squared portion 2O fitted within a similarly formed opening 21 in the blade body. The remaining threaded portion `22 of the shank which projects through the slot 15 receives thereon ay binding nut 23 having a. knurled manipulating portion 24. v

In use and operation, by loosening the nut 23 on the bolt, said nut may be employed as a manipulating handle for moving the blade longitudinally of the casing or housing. When it is desired to use the cutting edges' of the blade, the same is shifted to the position illustrated in Fig. 1 for projecting the extremity provided with the cutting edges 17 beyond the end of the housing after which the nut 23 is tightened to clamp said blade against longitudinal movement. The engagement of the lbody of the blade with the flanges or side walls 12 precludes any possibility of lateral lmovement during the use of the device. lVhen not in use, the nut 23 is loosened and the blade is moved longitudinally to retract the extremity having the actuating edges 17 Within the casing or housing whereby the same will be covered and protected. lVhen the actuating edges become dull and require sharpening, the blade, bolt or nut may be Withdrawn from the casing or housing bynmoving vthe bolt through the open end of the slot l5. The bolt maybe entirely removed from the iblade to facilitate the sharpening of the cutting edges. It will thus be seen 4that a highly y efficient and handy cutting implement has been provided which when associated With a supporting surface .eliminates the liability of displacement or loss .and leaves the users hand :free for handlingthe article to be: operated upon by the knife.

I claim:

The combination With a bench, machine,V

tached tothe upper supporting surface thereof comprising a -member having an upper Walland depending flanges at the side edges thereof, the said 4upper Wall having a longitudinal slot extending through one end thereof, vmeans for securing said member to the supporting surface to define With said supportingsurfa-ce a housing open at its opposite ends, a blade member arranged for sliding movement Within the housing having cutting edges at `one of its ends, .a threaded stem carried by said blade .and extending through the slot in the upper Wall of thefhousing, Vand a .nut engagedon said threaded stem constituting a nrauipulating vknob for project` ing 'the cutting edge of the blade from one end of the housing or for reti-acting the same vto lie Within the housing, said nut further constitutingmeans for clamping the blade in its retracted or projected positions.

JOHN TOOMEY.
